RISC5 Real-time Clock support

The attached file contains the source code of two modules RTC.Mod and SPI1.Mod which provide support in RISC5 Project Oberon for the Maxim DS3234 Real-Time Clock device. The DS3234 is a battery-backed chip that provides continuous time (hours, minutes and seconds) and date (year, month and day) info...

Re: STM32L432 Nucleo 32 board

I've just tried it with 3 x 1.5v batteries connected to +5V (CN4-4) and had the same problem. My multimeter read 4.85 volts which should be OK.

I also tried with a 9V battery connected to VIN (CN4-1) and that worked as expected. When it does work the ST_Link LED also flashes red.

Re: declarations and scope rules

I have done some more investigation. Further to my previous post: The other section of the report that is relevant to your question is 10. Procedure Declarations . In the original version of Oberon the visibility of local objects was as it is in Pascal: In addition to its formal parameters and local...

Re: declarations and scope rules

Your original quote omits some crucial information which totally changes its meaning: The scope extends textually from the point of the declaration to the end of the block (procedure or module) to which the declaration belongs and hence to which the object is local. Your expectations of the Language...

Re: declarations and scope rules

I apologise for the the delay in approving your first post. Any subsequent posts of yours will be accepted immediately. You can reuse identifiers in nested procedures. However, unlike Pascal and Modula-2, you can only access 'strictly local' or global identifiers from within a nested procedure. Hope...

Re: HCFiler compiling problems

Refer to the system requirements for HCFiler in the ReadMe.htm file. i.e. you need to use v6.2 of Astrobe to compile the source code as it uses some of the new features summarised in What's New in Astrobe for Cortex-M3 . The problem where additional (superfluous) bars were not allowed before the fir...

HCFiler - An efficient embedded SDHC FileSystem

HCFiler - the efficient embedded filesystem for SDHC cards announced recently in the Astrobe for RISC5 forum is now available for v6.2 Astrobe for Cortex-M3 targets. The total compiled code size of the 3 HCFiler modules is only 4 KBytes. It has been tested on the LPCXpresso LPC1769 and mbed LPC1768 ...

HCFiler - An efficient embedded SDHC FileSystem

Here is a 'sneak peek' of a pre-release version of HCFiler, the SDHC FileSystem which resulted from the discussion in April in the ETH Oberon Mailing list: https://lists.inf.ethz.ch/pipermail/oberon/2017/010537.html It is intended to be used for data-logging applications that might need to create fi...
